What it does Postiz schedules posts to a long list of platforms—X, Bluesky, Mastodon, Instagram, TikTok, LinkedIn, YouTube, and more—then adds analytics, team collaboration, and an API for automation via N8N, Make.com, or Zapier. It is built as a NextJS/NestJS monorepo with Prisma on PostgreSQL and Temporal for background work.

The interesting bit The project leans hard into “agentic” workflows: there is a separate Postiz Agent CLI for OpenClaw and other agent frameworks, plus a public API and official SDKs. The hosted and self-hosted versions are currently identical, which is either generous or a temporary state of affairs.

Key highlights

• Supports 14+ social platforms including newer ones like Bluesky and Threads
• AGPL-3.0 licensed, Docker-ready, with ~3M downloads claimed
• Official integrations: Node SDK, N8N node, Make.com app
• Team features with comments, collaboration, and post exchange
• Uses Temporal for reliable scheduling backend

Caveats

• “Many AI features” is promised but not detailed in the README; specifics are unclear
• Self-hosting requires PostgreSQL, Redis, and Temporal—not a lightweight deploy
• The “no difference between hosted and self-hosted” claim is current as of the README date, but not guaranteed

Verdict Worth a look if you are paying for Buffer or Hypefury and want to self-host, or if you are building agent workflows that need to post to social accounts. Skip it if you need a lightweight one-container setup or deep clarity on what the AI layer actually does.
